Building on top of wlroots is still a different scope of problem than writing a window manager for X. Pretending its the same thing doesn’t change the fundamentally different architecture even if it certainly makes it easier.
Out of all the libraries isn’t recent KDE the only fucking one that supports proper scaling of xwayland windows without turning it into a blurry mess? KDE which nice as it is lacks most of the nice tiling features of i3wm or the per monitor workspaces? Let me rip out and throw away a highly functional Nvidia GPU and come on down!
Don’t worry in another fucking 10 years all problems will be solved in the meanwhile I’ll just be fucking using non-beta software. Pardon me if I’m a little annoyed. Wayland has been the future for a while now.
